@Judy524, you are likely not seeing Shelby's profile because she doesn't have one. She may not have any reviews (yet) and users are not required to write up any type of profile information. I get bookings from 'blank' profiles all the time. Unfortunately, that is Airbnb.

You could ask Shelby to spend a moment and fill in a little bit about herself on her profile before you accept her request. Or you could use your judgement based on the communication you have with her whether or not you want to confirm her booking.
